Abstract. In atmospheric chemistry, a parameter called residence time is defined for each gas as T = M / F , where M represents the mass of the gas in the atmosphere and F is the total average influx or outflux, which in time averages are equal. In this brief communication, we extend this concept from matter to energy which is also a conservative quantity and estimate the average residence time of energy in the atmosphere, which amounts to about 58 d. A similar estimation for the residence time of energy in the Sun is of the order of 107 years, which agrees with the Kelvin–Helmholtz timescale.

简述：能量在大气中的停留时间

摘要。在大气化学中，每个气体的停留时间参数定义为 T = M / F ，其中 M 代表大气中气体的质量， F 是总平均流入或流出，它们在时间平均值上是相等的。在这个简短的交流中，我们将这个概念从物质扩展到能量，这也是一个保守的数量，并估计能量在大气中的平均停留时间约为 58 天。能量在太阳中的停留时间的类似估计约为 107 年，这与开尔文-亥姆霍兹时间尺度一致。
